Hello Robert,
I studied delaunay and mlab.griddata a bit while converting tinterp and
saw the
"""
tri = delaunay.Triangulation(x,y)
# interpolate data
interp = tri.nn_interpolator(z)
zo = interp(xi,yi)
"""
stuff. In studying delaunay, however, it was/is not clear to me how to
set up the "triangulation" for
delaunay.LinearInterpolator(triangulation, z, default_value=-1.#IND)
without going through delaunay. Any chance you could give an example of
using delaunay to linearly interpolate on mesh x,y assuming data_pts,
triangles, f_at_data_points are already given?
Best Regards,
Eric
